EXH'IBITING: 0R DISPLAYING APPLIANCE.

SPECIFICATION forming part of Letters Patent No. 629,232, dated July is, 1899. Application filed April 22, 1899. Serial 0. 714,031. (N0 model.) s

' To all whom it may concern.-

1 Hampshire, have invented certain new and useful Improvements in Exhibiting or'Dis- I playing Appliances and we dodeclare the following to be'a full, clear, and exactdescription of the inventiomsuch as will enable 0thers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an vplian ce for exhibiting or displaying cards and the like, the'exhibited or displayed device's Y being especially designed for use in connection with optical tests.

The object of the inventlon is to minimize Y the time and labor incident to the manipulatachment to a wall or other upright and contion of the varioustest-cards and the like; and to this end the invention consists of means by which the exhibition or displayof the test devices may be accomplished at a distance from the appliance, thereby enabling the optician to attend closely to the patient and obviating the present necessity of crossing the room at each time a change of a test device is required. Y

Our invention is designed also to overcome the present necessity of handling the devices in making the various tests, thereby insuring against loss of time and preserving the articles from damage and disarrangement.

The invention in all of its details is fully and clearly set forth in the following descrip- Y tion, in which reference is made to the accompanying drawings.

In the drawings, Figure 1 is a sectional view of an exhibiting or displaying appliance embodying our invention. Fig. 2 is a rear elevation, enlarged, of the casing containing the test devices. I

Referring to the said drawings by letter,

' A denotes a casing having a front 0., sides a ct, and top a The casing is adapted for at improved ap-i tainsthe test devices, suchas the cards B; which are introduced at the back, preferably left open,0r. at the open lower end. Y Attached to each of the cards isa condo, which is passed through an opening a in the top', there being preferably an opening for the cord of each card. Eachof the cords is passed around pulleysd d and is provided at its opposite end with a securing device, such asan eye 6,

which removably engages a pin f on the opp'osite patien'ts chair. Obviously any suitable securing device other than that shown maybe provided for each of the cords, and, ifdesired, the cords may terminate in suitable hand or finger holds. By-disengaging an eyee from its hook and elevating the end of the cord the card B, to which it is attached, is permitted sired, be augmented by a Weight, and said card is thus wholly or partially exposed at the will of the operator below the casing. When another test is to be applied, the cord is drawn down by the operator and its end secured, the card being raised within the casing, and another cord is manipulated to cause the proper card to be exhibited, and so on.

A stop 9 is provided to limit the downward movement of each card, which stop may, as shown, be secured to the cord to cause its engagement with the top a when the card is in its lowermost position, or this stop may be attached to the cord at any other point-as, for instance, near the opposite end-in which event the stop will engage a suitable shoul der-as, for instance, an eye through'which the cord passes or even one of the pulleys over which the cord moves.
